Abstract

This paper is aimed to review the current researches on Cold-formed steel (CFS) structures, particularly for screw connections, welded connections, bolted connections and adhesive connections. Connection presents as a major parameter of the important elements for CFS framing system in order to attain its structural stability. The performance of different CFS connections is well-discussed in order to capture the behaviour of each type of connection. Based on the review assessment, the results highlighted that all types of connections except adhesive connections have shown the proper behaviour that can trigger the change of any design codes. Otherwise, adhesive connection is given several advantages that leads a novelty in the construction technology. Hence it still has some gaps of knowledge that are needed to be filled with comprehensive future researches.

Abstract

The paper presents the dynamic behavior of a Submerged Floating Tunnel (SFT) in the Seribu Archipelago crossing under seismic loadings by using the different cable configurations. The SFT is a tubular structure submerged in the water at a fixed depth, which features several advantages from the structural and environmental impact points of view. In particular, the structural system is suited for waterway crossings in seismicity zones. Its interaction with the water provides additional damping and inertia to the system. To evaluate the SFT structural response of seismic loadings, a response spectrum analyses were carried out, in which the ground multi-support excitation is considered. The investigation of the different cable system configurations were also carried out. Both static and dynamic analyses were carried to find the optimal configuration of the structural system. Although the paper has had a definitive conclusion yet, the results gave useful indications of responses of Submerged Floating Tunnels subjected to earthquake. The SFT with two cable diagonals perpendicular with SFT’s body (called Model C) shows the optimal structural configuration compared with others.
